Great fit...but 1" shorter
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Fit and quality is great. However the shortblade needs to be 21". OEM is26" and 21". Bosch sets 26 and 20". I may have missed, but I didnt t see anyone mentioning this issue.
Other than that is perfect fit.

Terrific Bosch blades
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
These German made wiper blades do their job so well that my wife was impressed. Once you get the hang of it they are one minute to replace. Recommend placing a cloth under the blade to avoid any windshield scratches if the metal wiper assembly accidentally falls down on the glass. Nice to see the Bosch name on the wiper blades.

Best replacement option for 2025 Tesla Model Y Performance
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Outstanding replacement option for 2025 Tesla Model Y Performance (Pre-Juniper), so much smoother than the OEM wipers. Very easy to replace. They seem very durable after testing on all wiper settings. Definitely keep the windshield clearer without streaks. Seem to also have more stability on mounting compared to OEM option. 15/10 replacement for the cost, can’t beat it.

Reliable and Essential Power Steering Fluid for Honda Vehicles
I recently purchased the Honda 08206-9002PE Power Steering Fluid to top off the power steering reservoir in my Honda Accord. The process was straightforward: I drained the old fluid and replaced it with this Honda-specific fluid. The difference was immediately noticeable.
The fluid is designed to meet Honda’s stringent specifications, which is crucial for maintaining proper steering performance and longevity of the power steering components. After adding the new fluid, the steering response was noticeably smoother and quieter. There was a reduction in the whining noise that sometimes occurs with old or low-quality fluid.
The pack of three is very convenient, offering a good value and ensuring that you have extra on hand for future maintenance. The bottles are well-sealed and easy to pour, with no spills or messes.
One of the benefits of using the Honda 08206-9002PE fluid is that it’s formulated to prevent foam and protect against corrosion, which helps in extending the life of your steering system. It’s always reassuring to use a product that is specifically recommended by the manufacturer.
Overall, Honda 08206-9002PE Power Steering Fluid is a high-quality product that delivers excellent performance and reliability. It’s a great investment for anyone looking to keep their Honda’s power steering system in top condition. Highly recommended for its effectiveness and value!
